Size the basket perforation. As a general rule, the mesh or perforation should be designed between 1/2 to 3/4 the size of the equipment manufacture's recommended size.

For example:	If a pump is designed to handle 1/8" diameter solids. Size the basket as follows:

	0.125 x .75=0.9375 use 3/32" perf (2mm)
		or
	0.125 x .50=0.062 use 1/16" pef (1-1/2mm)

Because of cost, we would select the 3/32" perf (2mm). It has the larger open area percentage.

Note:	Do not specify an opening too small thinking that smaller is better. A small opening will cause more expensive equipment and higher maintenance costs.
